The nearly three-meter-wide metal ring, which was located around the top of the DR3 reactor tank, has been successfully lifted out. Similar to the lift performed earlier this year, today's operation was executed with high professional expertise from the Dutch company Mammoet and custom-fabricated equipment from the Aalborg-based company Bladt Industries.
Concrete dust, grinding machines, and full-body suits. Much of the time, decommissioning resembles a rather ordinary, yet intensive, renovation. The powder room, where Risø processed uranium for fuel rods, has been thoroughly ground down on all surfaces.
It is late afternoon over Risø, and the shadows from the silver poplars have lengthened. However, DD's security personnel remain on duty, even as the lights in the offices are switched off one by one. Personnel are always present at the Risø site, around the clock, year-round, where DD's guards, among other duties, patrol and inspect the buildings and collect samples.
At next year's review meeting of the UN's Joint Convention, a DD employee will be at the critical end of the table. Health Physicist Haraldur Hannesson has been appointed to the panel, which will participate in evaluating, among others, the United States' management of radioactive waste.
In May 2014, Danish Decommissioning carried out a major operation, successfully lifting a highly radioactive metal plug from Denmark's largest research reactor.

On the upcoming three Thursdays in July, you can take a guided tour of the Risø area and gain an impression of the former research center. The tours will be conducted regardless of weather conditions on the following dates: July 3rd, July 10th, and July 17th. Registration is required.
In May 2014, Danish Decommissioning carried out a major operation: lifting the 22-ton heavy metal plug from Denmark's largest research reactor DR3. The actual lifting of the plug took one hour, and the operation can be viewed in timelapse here.
Attend the Open House at Danish Decommissioning and learn about our unique environmental mission at Risø: Friday, June 13, 3 PM-6 PM.
Success: The massive metal plug that sealed Denmark's largest research reactor DR3 has been successfully removed and replaced with a lid. Due to intense radiation from the reactor tank, this historic operation has been meticulously planned over recent years. DD commends the collaboration with Mammoet and Bladt Industries.
